Scuba Diving Cave Markers

Some cave markers, including an arrow, a cookie, a hex cookie and a REM.  
All models feature a distinct ridge, making it easy to identify them with your hands.

Printing instructions:

• 0.1mm or 0.2mm layer height (the models are optimized for it!)
• 0.45mm extrusion width and 3 perimeters/walls (the wall thicknesses are optimized for it!)
• 100% infill is recommended to avoid water entry. But it's not a must, 1mm thick top and bottom layers already result in negative buoyancy.
• use a material that offers the needed chemical (and UV resistance). I recommend PETG or ASA.
